As a self-described newbie, you are doing what you should, i.e., gathering info and researching here and (hopefully) other sources. One word of caution: many engine builders are sensitive about accepting advice from an owner who got his knowledge from "online friends".
I suggest that your research should include which builder will work best for your needs, then discuss options with him. There is nothing wrong with asking questions. That's how we all learn. How you apply that learned knowledge is another type of skill that sometimes comes from experience. Best of luck as you move forward.
